Hi, I'm curious if anyone has heard about and actually tried out the rollaway nest boxes where the nest is sloped at an angle and when an egg is produced, it rolls down the slop to a spot outside the nest box. They say this prevents egg eating and also keeps the eggs clean. Also, this book I'm reading recommends using that fake plastic grass for the nest box as it is easy to clean. Any thoughts would be greatly appreciated as we haven't yet built our nest boxes and I'm interested in knowing the pros and cons of this. Thanks in Advance!
